[#5359] fix(ob-catalog): fix ob catalog default value parse error (#5378

) ### What changes were proposed in this pull request? fix ob catalog default value parse error ### Why are the changes needed? For OceanBase catalog, the `IS_GENERATEDCOLUMN` value of the column ResultSet is set to `NO`, which is causing `isExpression` to be false and leading to a parse error. Fix: #5359 ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? tests added
